I need help with this

Answer 1

Check step-by-step explanation.

Explanation:

1. Form a table for the given equation.

In order to form the table, we must take several values of x (any values you want to evaluate) and find it's correspondent y value. This is how you do it:

`y=3x+12`

`x=0, \\y=3(0)+12\\y=12`

As you may notice, we are just substituting the x value for the x variable into the equation and calculating y. Do this with several values and form a table (check attached image 1).

`x=1, \\y=3(1)+12\\y=15`

`x=2, \\y=3(2)+12\\y=18`

2. Draw the points.

Using the calculated points, draw them in the cartesian plane. Remember that "x" means how many spaces you move horizontally, and "y" means vertical spaces.

Check attached image 2.

3. Interpret the information.

Let's take point (2, 18) as an example. This point is generated when you substitute the x value of 2, meaning 2 hotdogs and the souvenir hat. Then, the functions gives a result of 18, which would be the cost of those 2 hotdogs in addition to the souvenir hat. Point (0, 12), on the other hand, means that you didn't buy any hotdogs but you still have to pay $12 for the souvenir hat.
